Patent GB-138646-A (GB)
Abstract: 138,646. Dayton Engineering Laboratories Co., (Assignees of Hunt, J. H.). Nov. 11, 1918, [Convention date]. Interrupters, mechanical; rotary distributors; timing-devices.-For engines in which the intervals between successive sparks are not all equal, interrupter arms and contacts unsymmetrically placed with reference to the axis of the actuating cam are provided and are used in conjunction with a distributor rotor having brushes relatively placed to deliver the impulses in the necessary non-symmetrical succession. Induction coils 20, 21 are connected to a battery and in parallel circuit to the terminals 27, 30 of the interrupter mechanism 28. Insulated contact-closing springs 38, 39 conduct the two branches of the current to the contacts 34, 36 and 35, 37 mounted on the arms 32, 33 respectively. These arms are not placed diametrically opposite thus giving unequal firing intervals. The currents from the secondary windings 72, 73 pass by way of terminals 64, 62 to strip 66 and brush 68, thence to brushes 67, 69 respectively in the distributor rotor 47 which is mounted on the upper end of the shaft 45 carrying the cam 46. The brushes 67, 69 are not dimetrically opposite one another but are displaced in correspondence with the arms 32, 33, so that current is distributed to the cylinders at unequal intervals. This firing order is suitable for an eight-cylinder engine of the 45 degrees V-type with crank throws at 180 degrees. The brushes may be arranged on an arm at different radial distances, the fixed segments being positioned above the brushes in two concentric circles. In this case, the secondary currents are introduced by a binding post having a contact centrally placed in the distributor head and by a second post adjacent to the first but leading to a ring in the head. Brushes in the rotor are in permanent engagement with the contact and ring and by means of insulated leads conduct the currents to two other brushes which successively engage the contacts connected to the plugs. In another arrangement, the two brushes are placed on an arm at an equal distance from the axis and are separated by an appropriate angle. They are fed by a central post and strip and a segment mounted in the periphery of the distributor head. Automatically actuated means, consisting of a centrifugal governor 44, and manually actuated means comprising a slidable sleeve engaged by a pin which also projects through oblique and straight slots in the shafts 41, 50 are provided for controlling the timing of the ignition.
